Ubuntu cron日志开启与查看的实现步骤
<p><strong>Ubuntu cron日志开启与查看的实现步骤</strong></p>
<p>
ubuntu默认没有开启cron日志记录</p>
<p>
<strong>1. 修改rsyslog </strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_631411">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">vim </code><code class="bash plain">/etc/rsyslog</code><code class="bash plain">.d</code><code class="bash plain">/50-default</code><code class="bash plain">.conf </code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="bash functions">cron</code><code class="bash plain">.* </code><code class="bash plain">/var/log/cron</code><code class="bash plain">.log </code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
#将cron前面的注释符去掉</p>
<p>
<strong>2.重启rsyslog </strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_305706">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">service rsyslog restart</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<strong>3.查看crontab日志 </strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_482265">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">tail</code> <code class="bash plain">/var/log/cron</code><code class="bash plain">.log</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
默认cron会发送邮件把任务的运行结果比如错误信息发送到系统用户的邮箱中，而不会在log中出现具体的脚本运行输出的信息，所以我们可以指定一下每个任务的输出日志路径：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_537111">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">0 2 * * * db_backup task; >> </code><code class="bash plain">/var/log/db_backup</code><code class="bash plain">.log 2>&1</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
这样我们就可以去相应的日志文件查看脚本输出结果了。</p>
